Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?
True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.

Is asphalt made from petroleum?
Yes, asphalt is made from bitumen, a type of petroleum.
What materials are needed for asphalt road construction?
Asphalt road construction primarily requires asphalt binder, which is a petroleum product, and aggregate materials such as crushed stone, gravel, or sand. Additionally, additives may be used to enhance the performance of the asphalt mix, including polymers or recycled materials. Equipment for mixing, laying, and compacting the asphalt, such as asphalt pavers and rollers, is also essential for the construction process.
Does asphalt have glass in it?
It's not supposed to. Asphalt is a petroleum derivative (the stuff left after all the volatiles are removed), and there may or may not be rocks (crushed stone) added.
What are some of the ingredients used by an asphalt plant to make asphalt?
In order to make Asphalt many ingredients are needed. The exact ingredient list varies by company but usually include Asphalt cement, crushed rock, asphalt plant, Petroleum compounds, water and mineral fillers.
Calculate gallons of asphalt cement in a ton of asphalt?
The answer is, it depends. Different types of bituminous cement concrete (asphalt hot mix) use different percentages of asphalt cement. In Virginia, base mixes use at least 4.4% asphalt, while surface mixes are up to about 6%. Liquid asphalt is a little heavier than water; it weighs about 9.4#/gallon (depending on the source and grade). Here's the math: Base mix 2000#/ton x 4.4%/9.4#/gal. = 9.36 gal/ton surface mix 2000#/ton x 6%/9.4#/gal. = 12.76 gal/ton hope this answers the question.
Why is asphalt not called tar?
It is in some places. These days asphalt and tar have apparently come to have the same meaning ;- A dark bituminous product from coal or petroleum ,used in surfacing roads.
From what sources is asphalt derived?
Most asphalt is obtained as a byproduct of the distillation of petroleum or other natural materials. Some natural asphalt, however, is extracted from organic mineral deposits in the early stages of their breakdown
What is 'bituminous macadam'?
how many density of 'bituminous macadam'?
Is bituminous material is the same for bituminous concrete if not why?
No, bituminous material and bituminous concrete are not the same. Bituminous material refers to the binder, typically asphalt, used in asphalt pavement mixtures. Bituminous concrete, on the other hand, refers to the final pavement product made by combining bituminous material with aggregates like sand and stone.
What is the difference between bituminous coal and bitumen?
Bitumen is a highly viscous product of the decomposition of algae and other organisms deep underground. Bituminous coal is the solid product of the lithification of mostly plant remains by overburden pressure.
Is asphalt made from petroleum?
Yes, asphalt is made from bitumen, a type of petroleum.
What is asphalt pavement?
Asphalt (petroleum tar) mixed with gravel.
What substance obtained from petroleum is used for covering on roads?
Tar is obtained from liquid petroleum. Tar is used as a hot liquid covering under gravel to build roads. Note: Asphalt is made from bituminous coal pitch, mixed with sand or gravel. The black color comes from coal pitch, not from petroleum, as does tar.
What is bituminous material?
Asphalt coal tar Tar sands Brown coal
What are byproducts of asphalt?
Asphalt is itself a byproduct of coal gas generation or oil refining.
Is asphalt a kind of rock?
No, asphalt, aka bitumen, is a form of petroleum.
What is the abbreviation for asphalt?
AC is an abbreviation for asphalt. The terms "asphalt (or asphaltic) concrete", "bituminous asphalt concrete" and the abbreviation "AC" are typically used only in engineering and construction documents and literature. ASPH or AP is the abbreviation of Asphalt.
